鱼腥草白绢病的发生与防治

鱼腥草属药食两用植物,具有清热解毒、健胃消食、利尿通淋、增强机体免疫力等功效。鱼腥草是桂林市农民增收的重要经济作物之一。近年来,由于连年种植,导致鱼腥草白绢病发生严重,已经成为阻碍鱼腥草生产的一大因素。本文总结了鱼腥草白绢病的发病条件和规律,提出了鱼腥草白绢病的防治方法,即避免连作、科学选地、选种及种茎消毒、合理施肥、加强管理等,以期减少白绢病造成的损失,科学有效地防控白绢病的发生。     

A conceptual model of farmers' decision-making process for nitrogen fertilization and irrigation of durum wheat

With a 2 millions of tons production, France is the second country in the European Union to produce durum wheat. Durum wheat production requires high grain nitrogen concentration. Irrigation and nitrogen fertilization must be managed simultaneously to maximize grain yield and also avoid low protein concentration and environmental impacts. To help advisors and farmers to better manage together these two agricultural operations and to develop innovative managements, developing a biodecisional model is an interesting possibility. However, knowledge is still missing on how farmers already managed these operations and how these two operations are linked. We developed the conceptual model for the decision part of this computer model. We performed a survey of 28 farmers conducted over the five French production areas investigating a diversity of growing conditions to identify the set of possible constraints and farmers' decision rules. To analyze the survey, we first used a general inductive approach on individual cases and then built a conceptual model of the decision with a bottom-up approach. We identified four decision sequences for fertilization (N splitting, choice of N fertilizer, rate of application, fertilization triggering) and five for irrigation (irrigation period, anticipated number of irrigation cycles, irrigation cycles organization, irrigation triggering and irrigation cycle specificities). For each operation, the first three decision sequences refer to strategic decisions. The other decision sequences refer to tactical decisions. Coupling this model with a crop model could provide guidelines for managing durum wheat in the current climatic and economic changing context.
